Solutions

Ensotek cooling towers operate on an induced draft, counter-flow principle. Hot water from the facility is distributed from top to bottom across the tower cross-section, while ambient air is drawn in through side louvers, absorbs heat and moisture, and is discharged through the fan stack. Cooled water is collected in the basin at the bottom.

Thanks to the modular design, towers can be lifted and relocated when required. Material compatibility and corrosion resistance (FRP/CTP, PVC, PP, stainless fasteners, etc.) support long service life and reduced operating/maintenance costs.

Solution Areas

• Industrial Cooling: High-efficiency tower solutions for manufacturing plants, power generation and demanding operating environments.
• HVAC Cooling: Stable approach temperature and energy optimization for commercial buildings, shopping malls and hotels.
• Process Cooling: Open/closed circuit selection and auxiliary components for processes where water quality is critical.

Open vs. Closed Circuit Selection

Open circuit towers are widely used due to high heat transfer and broad capacity range. Closed circuit towers are preferred when the process fluid must remain clean: the process water is cooled through coil pipes, reducing contamination risk and improving operational stability.

Energy and Performance

In induced draft towers, fan power consumption is generally lower than forced draft alternatives. Because humid air exits at higher velocity from the top, recirculation risk is reduced and performance is preserved. Therefore, induced draft designs can provide approximately 1.5–2× energy savings compared to forced draft towers (application-dependent).

Materials and Component Standard

• Tower body: FRP/CTP sandwich panels reinforced with ribs; isophthalic/vinylester and flame-retardant options upon request.
• Exterior surface: UV/chemical/corrosion resistant, paint-free gel-coat.
• Structural system: FRP pultrusion profiles including service ladders and platforms.
• Fan group: Axial fans; tip speed typically 52–60 m/s.
• Motor/Gear unit: IP56 protection, class F insulation, V1 vertical flange type; motor-only or motor+gear depending on fan diameter.
• Water distribution: PVC / PP / FRP; typically PVC below ~55°C, PP/FRP for higher temperatures.
• Fill selection: PVC film fills for clean water (max ~55°C), PP ring fills for high temperature (~100°C), splash grid fills for very dirty water.
